14 Claims.

,Ti' isinvention relates to shuttles for weaving and especially to what,are called automatic shuttles such as are used in automatic bobbin,

changing looms. In this type of loom there is a battery, chute er-magazine which holds a numberof fullbobbins, one of which replaces anempty or almost empty, bobbin in a shuttle after a feeler locatedsomewhere in the loom indicates that the thread on such bobbin is almostexha'usted. I

Generally the full bobbin is forced down by a transfer hammer into theshuttle, taking the place of an empty bobbimthe end of its thread beingattached to some part of thebattery, magazine or to someother part ofthe loom.

the first pick, the shuttle carrying the new, full bobbin is drivenacross the loom and on the next pick it is driven back. In shuttleswhere there is a shuttle eye outlet in the side, the thread cannot getpermanently into the eye out,- let so that it is permanently trapped,until the second pick after transfer, because it must get around a noseand changeidirection almost ninety degrees. i

1 Most such shuttles have a nose extending forward at or near the top ofthe shuttle with ahook of some sort extending ldown near'its top so thaton the first pick the thread drops down under this nose and is caught bythe hook. There is also what is known as a horn'which extends :down andback from at or near the nose, this horn having a hookat the bottom, thepurpose being to cause,

the thread on the second pickto slip down along the front of the hornbehind this hook into a thread delivery passage to an eye outlet whereit will be kept by :the hook, as a, trap, while the thread on the newibobbin is running out.

There is also a central vertical inside thread postaround whichtheflthread bendslat an angle of about ninety degrees. r

Ordinarily'there isan axially extending threading slot and .a top threadgroove in front of it. There is also an eye threading slot extendingdown and back at an angle from in front of the nose to a shuttle eyeoutlet.

With mydevice, there is no axial, forwardly extending threading slot, notop groove, no vertical, central inside post, no nose, no horn, and noangularly backwardly extending eye threading slot.

The main feature of my 'device is a single threading slot and threadp'assage which extend from the front of the "bobbin chamber straight anddiagonally toward and out "the Side 0f the shuttle into a thread grooveas a shuttle or thread eye outlet. u

The thread delivery eye passage forms part of this threading slot orconnects with that slot at its bottom, both the slot and the threaddelivery eyepassage being substantially straight.

Another novel feature of my device is the trap at the thread or shuttleeye outlet, which outlet is at the front end of the threading slot andof the thread delivery eye passage. The purpose of this construction isto cause the thread to slip down into and through ;the threading slotright into the trap and into the thread delivery eye passage and shuttleeye outlet on the first pick or at almost the instant the shuttle startsto move along the shuttle race on the lay on the first pick aftertransfer.

7 This shuttle eye outlet is so made, preferably with two verticaloutlet pins, that as soon as the threadis in the trap it remains thereand runs between these outlet pins until another bobbin is transferred.In other words, it is fully and finally threaded, r

I alsoprefer to provide the thread passage at its inlet with frictionplates which also serve as thread guides or with a thread pin so placedthat the thread makes no bend and touches: nothing after leaving theplates or pin until it runs around one of the Outlet pins into thethread block is used in a shuttle body made of wood or other material,with my device many parts are eliminatedand many processes are avoidedbecause I Qan use a threading block with substantially parallel sides,bottom and top, which block can be slipped in at an angle from the eyeside to a sim larly bored and cut block recess, or hole.

Moreover, the thread delivery passage in the block can be drilled as astraight, cylindrical hole and the threading slot can be cut as straightpassages with a straight saw. a

The threading block can be held in place by suitable wings, ribs andgrooves of different kinds and by a blockscrew in such a way that-theydo not Weaken the shuttle.

By omitting the usual threading slot which runs axially and beyond whichis a top groove, there is more stock at the front of the shuttle and thetendency to split at that point is greatly reduced.

The wear pins at front and back at the eye outlet can be made of veryhard metal, porcelain or other 'wear resisting material and can be heldentirely in the metal threading block instead of in the wood therebyrendering the construction stronger and allowing them to be easilyreplaced.

The entire construction of the threading block is much simpler thanwhere an axial threading block with wings sunk in the wood, a forwardnose, a horn and irregular passages is used as in the usualconstruction.

By making the sides. and bottomof the thread ing block cylindrical, itcan be slipped into a drilled hole in the side of the shuttle body andas in this construction the block is held on they sides, part of the topand at the bottom, it does not rock on the attaching screw and causetrou desirable to help balance the shuttle, my device canbe used as partof a shuttle made of plastic or other material with no block of anykind.

A shuttle of my construction can of courseloe V threaded by hand.

Fig. 26 is a diagrammatic, horizontal sectional view through atypicaloutlet for. a thread delivery eye passage such as shown in Fig. 25 as online26---26.

In the drawings, S represents a shuttle of the automatic type having atip I which I will call the front tip, a thread groove 2 along the sideof the delivery eye passage outlet 2| and a bobbin recess 3 in which abobbin B is shown as held by the usual holder ll, l2 representing thetip of the bobbin.

The above parts are substantially the same as in most automaticshuttles, the thread groove 2 which runs along the eye outlet side ofthe shuttle being to receive th thread T after it has com from thebobbin B and out through the eye, all in a well known manner.

' 4 represents a threading block recess which extends; from the middlefront IU. of. the bobbin recess 3 diagonally forward to a position attheeye side and at the thread groove 2 between the front tip and the frontll] of the bobbin recess 3.

As shown in Figs. 1 to 7, there is a mouth E,

to receive the thread '1, at the top of this block recess, formed by thewooden lips at 5, '5, which converge and extend downwardly while thesides 6, 6, are'parallel and the bottom at is substantially cylindricalin cross section.

A represents athreading block which in cross section substantiallyconforms to the shape of the block recess 4 whereby it can be slipped infromthe outsideor slipped out if it becomes necessary to remove it. c 1

The front'part H) of bobbin recess 3 enters block recess 4 and Hi is arecess for friction plates}, 9, if they are used, and may beconsidered-an extension ofor part of eye passage 20. The eye passage 20extends lengthwise through the thread block A, parallel with its sideand bottom walls, from the back or inside end I9 and the recess H? forth friction device G, including the plates 8 and 9, to its outside end2| which I will call the eye passage outlet. At this end just inside theoutlet 2| is the thread trap V which includes a hook 23, thread passage28 and trap thread guide 21.

Where a block such as A is usedE indicates the mouth which includes theconverging lips 5, 5, in the shuttle bodyand'the lips 25, 25, in theblock A. a This mouth and these lips are so made that-they so'converge'as to direct the thread T int-o the'threading slot C and trapV. This threading slot C includes the part 22 which extends from themiddle of the top near the back of eye passage 2!) forward andpreferably at a slight angle away from the eye passage outlet and downat a tangent or near tangent to the front'of that passage just behindthe trap V as shown'in' Figs. l'and Z'and 4 to 7 This part 22st the slot'0 stops just before it reaches the trapthread guide 21 and turns at 28at about a right angle between the trap hook 23which is formed when itis being cut and the trap thread guide 2|,*Figs. 1,'4A, 6 and 7. 1

It will be observed that this trap thread guide 21 blocks the front. endof the part 22 of the threading slot C and that at the front or outletend of the'block A, the lips 25,25, merge with the top faces or edges ofthe trap hook 23 and of trap thread guide 2Twhich'faces are preferablyformed on, curves which slope in and down in opposite directionstowardseach other and which intersect at a point'slightly above the threadcenter by the transfer the thread T is directed by the mouth, suchas E,intotheback endof the threadingslot C and when once started in thatslot, thefiensionpn the thread as it partly untrap thread guide 21.

winds from its bobbin to the point where it is attached to the magazine,causes it to slip along lay moves from front to top center, the up anddown movement of the thread as it unwinds, beingconiined betweenplatessuch as 8 and 9, and

the snap of the picker action combined with the backwardmovement of thelay, carries it down around-and under both parts of thetrap V namely thehook 23 and the guide 21 and through the slot part 28 into the eyepassage 20 although usually the hammer action of the transfer itselfcausesthe thread to get into the eye passage before top center.

Where a threading block is used, Ifind it convenient to cast it with thesides of the threading mouth converging and extending down to where thethreading slot will be cut. The front part where the thread trap willbeis also suitably formed.

The eye passage 20 is bored or drilled, preferably parallel with thesides of the-block, the parts 22 and 28 of slot are cut down into theeye passage, with 28 at a right angle as in Fig. 1 or at t l a differentangle asin Fig. 13. The out part 28 forms {the trap hook 23 andseparates it from the The thread groove 26 is cut and holes I6 and I Ifor pins P and F are drilled upfrom the bottom-across groove 25 where itintersects passage 20 and all sharp and rough edges are removed.

Extending down from under the thread guide 21is a vertical front outletp'inF which extends across part of the thread groove 26 and across thefront part of :the eye passage outlet 2|.

P is a vertical back outlet pin which extends across part of the threadgroove 26 and across the back of the eye passage outlet 21 and 8 and 9representfriction plates of a well known kind which slope forward anddownand at the top have diverging lips I5, IS, in a position to receivethe thread as soon as it starts unwinding from the tip 12 of the bobbinB on the first pick. These plates and particularly the one 9 on the eyeside keep the thread T in the middleo'f the eye passage 20 until itengages either one of the pins F or P. After it leaves either one ofthese pins, it continues in the thread grooves 2 and 26 at no placecoming in contact with any rough surfaces which might injure it.

D is a'fastening screw which as shown in Figs. 1 t0x10 passes downthrough a hole 28A in threading block A and into a nut 29 sunk in thewood of the shuttle S. l

Blates ii and 9 of friction member G are movable on a pin I3 and arepressed together by springs I4, 14. Pin i3 holds up thread T clear r ofthe =bottomof eye passage 20.

the threading block construction in which the block :is indicated by 0.Its cross section, as

shown in Fig. 11, is relatively rectangul'ar instead ofcylindric'al-asis also the recess 4| into which The "body of the shuttle is cut away at,40, and the opening and lips 42, 42, of the threading slot 43-allconverge to direct the thread through-thethreading slot 43 and into thethread delivery eye passage M. r

The trap hook 45 and thread guide 45 are substantially the same as inthe other construction but the attaching screw 41 passes through thehorizontal hole 49 in the body and 48 in the block instead of extendingdown vertically.

In Figs."14, 15, 1'6, thethreading block K is shaped in cross sectionvery much like A but on each side has the longitudinal grooves 50, 50,which engage the ribs or projections 5|, 5|, extending into the blockrecess 52 whereby the block-is locked in place. The converging lips 56,56 in the wood may be small in this case. The converginglip's 54, "54are all that is necessary and the fastening means is shown as twovertical screws or pins 55, 55, which extend down from the top of theblock through the projections 5|, 5|, thereby locking the deviceentirely and firmly in place.

As shown in Figs. 17, 18, 19 the threading block may be entirely omittedas Well as the friction plates and the outlet pins. In such a shuttle H,the lips 60, B0, connect with the threading slot 6| which enters orforms part of the thread delivery eye passage 62 with a trap hook 63 andthread guide 64, the outlet pins being replaced by rounded surfaces 65,65, and the friction plates being replaced by felt pads El, 61.Preferably there is one rounded guide rib 65 at the inner end of passage62 on the eye outlet side.

The characteristics of my device are that my threading slot starts atthemiddle top of the front of the bobbin chamber so that thread, woundeither way, will slip into it as soon as the lay starts to move back, oreven before that if I use a friction device of the friction plate typewith the friction plates sloping down and forward, as the thread isinstantly caught and is held in line with and starts through the back ofthe threading slot.

The slope of the mouth such as E, at the back or near the'bobbin tip,down to the back entrance of the threading slot should be at a steepangle, the front or eye side being preferably steeper than the otherside, as shown in Figs. 8, 9, and 10.

While preferably my threading slot extends from the back, forward anddown at a small angle with the axis of the thread passage away from theoutlet side so that the thread after it starts in the slot is beingconstantly pulled down until it engages the thread guide which extendsfrom in front of the end of the threading slot out and down beyond thefront and bottom part of the trap hook formed by the cutting of thethreading slot, this threading slot may run parallel with the axis ofthe thread passage, provided the'thread guide extends in front of itover and down below the trap hook so formed whether it is down at thesidenear the bottom or at the top.

As my threading 's'lot starts at the middle top, the whirling orunwinding of the thread from the bobbin is of no help nor hindranceexcept that as the thread unwinds, it moves up and down between thefriction plates and the downward motion, when combined with the diagonalpull along the axis of the thread passage as the lay moves back and theshuttle starts its pick, carries the thread down through the threadingslot, around the trap hook and down over the thread guide until it issafely locked in position,

On account of the shapeof the trap hook and its association withthethread. guide it makes no difference which way thethread-shpsaroundthe eye outlet, as it willbe stoppedby the thread threaded, will slipdown below. and betweenit' and the bottom of the cooperating trap hookor will slip down off the trap hook, around the tip or nose of thethread guide but cannot escape. W

The top faces of thetrap-hook and; of the trap guide curve or slopesothat they intersect and the bottom face of the guide comes below the tipof the hook as shown enlargedand exaggerated in Fig. 25. V

In Figs. 20 to 24, I show various combinations and modifications of thethreading slot, thread passage, trap hook and thread guide. I

In Figs. 1 to 10, slot 22-is at an angle with the axis of passage 20,and hook 23 is at the right as is guide 21.

In Figs. 20 and 21 the threading slot 32 or 82 is at the top andparallel with the axis of thread passage 30 or 80, so that hook 33or 83and guide 3! or 8'! are near thecenter of the eye passage and in Fig. 22the hook 84 and thread guide 85 are over at. the left. p r

a double thread delivery passage formed'by holes 99 and 9| connected bya secondary threading slot 92, the primary threading slot being shown at93 and forming the trap hook 94, while the thread guide 95 extends welldown beyond and in front of it.

' In Fig. 24 is shown a double thread-passage formed by holes 96 and 91connected by a slot 98, while 99 is the threading slot connecting withand forming trap hook I in front of which extends the thread guide IOI.

In my preferred construction, where I use a metal threading blockextending diagonally such as A, O, or K, to keep the shuttle wellbalanced, leaving the front part of the shuttle near the tip with morewood or other material than in the usual construction, I bind theshuttle'body and block together by a bolt or screw. I thus secure astronger construction and one which will resist the constant pounding ofthe loom.

If the block such as A, O, or K is inserted through a hole in which thematerial of the shuttle body overlaps part of the block or if one or theother has ribs or channels, any tendency of the block to loosen andpivot on the fastening device is stopped.

Fig. 25 is an elevational view and Fig. 26 is a horizontal sectionalview, both diagrammatic ,and

enlarged, of a typical outlet of a thread eye passage showing thepreferred shapes and positions of the trap hook and guide and of theoutlet pins such as P and F with reference to a thread eye passage suchas 20 and a thread groove such as 26,'which forms part of'the threadeyegroove such as 2 in the body of the shuttle.

Fig. 26 clearly shows that, preferably, pins P and F or theirsubstitutes 65, 65, are so positioned that they intersect the walls of20 and 26 so that each projects a little distance into both the.

eye passage and into the thread groove.

Preferably the bottom edges of the thread trap hook and guide are in thesame curve, and the bottom edgeof the guide should not be above assmssthejbottom edge of the hook but itmay extend below that edge and down infront of thetoppart of the eye passage, and of, course it: should beoutside and spaced fromthe trap hook.
